FOREIGN PRIORITY

This application claims priority to Chinese Patent Application No. 202022732306.X, filed Nov. 23, 2020, and all the benefits accruing therefrom under 35 U.S.C. § 119, the contents of which in its entirety are herein incorporated by reference.

TECHNICAL FIELD

This disclosure relates to the technical field of air conditioning devices, especially to an electric cabinet of an air conditioner and an air conditioner with the electric cabinet of an air conditioner.

BACKGROUND

When an air-conditioning device is running for a long time, electronic components inside the electric cabinet will generate heat. When the heat cannot be dissipated or the heat dissipation is not good, it will seriously affect the normal operation of the machine and the service life of the electronic components. Moreover, air-conditioning equipment will also be installed outdoors, facing the problem of waterproof and rainproof. In conventional compact electric cabinets, some only consider heat dissipation, and some are able to perform heat dissipation and rain protection at the same time. However, the heat dissipation channel is small, resulting in poor heat dissipation; and the design of an air duct structure is defective. In order to prevent rainwater from entering the inside of the electric cabinet, air vents are designed to be misplaced, which causes the air duct of the box body to be blocked, affecting the heat dissipation efficiency of the electric cabinet body.

DETAILED DESCRIPTION

It should be understood that the specific embodiments described here are only used to explain this disclosure and are not used to limit this disclosure.

With reference to FIGS. 1 and 2, this disclosure provides an electric cabinet of an air conditioner, comprising box body 1, bottom plate 2, and ventilation cover plate 3. Bottom plate 2 is installed at the bottom of box body 1, ventilation cover plate 3 is installed at the bottom of bottom plate 2 and forms cavity 4 with bottom plate 2. Air vents 21 are provided on bottom plate 2, shutters 31 are provided on ventilation cover plate 3, and shutters 31 are aligned with air vents 21 on bottom plate 2.

Box body 1 is used to install and electrically control main electronic components, circuit boards, etc.; bottom plate 2 is used for air intake and protection; and ventilation cover plate 3 is mainly used for ventilation, heat dissipation, and rain prevention of the electric cabinet.

Shutters 31 are aligned with air vents 21 on bottom plate 2. It may be understood that after entering cavity 4 from shutters 31, wind may directly flow out through air vents 21 since shutters 31 are aligned with air vents 21, thereby reducing air duct resistance and improving heat dissipation efficiency of the electric cabinet.

It should be noted that the electrical components in the electric cabinet are compactly arranged and generate a large amount of heat. Electrical components under high temperature have great safety risks. After ventilation, the heat of electrical components can be taken away in time to prevent the electrical components from being damaged under high temperature. As shown in FIG. 4, a plurality of air vents 21 are arranged on bottom plate 2 in a spaced way, and shutters 31 are arranged in an array on ventilation cover plate 3. Wind flows into cavity 4 from the direction of the arrow shown in the figure, and may flow directly from air vents 21 into box body 1 without turning to cool down the electrical components inside the electric cabinet. Hence, by aligning air vents 21 with shutters 31, the air duct resistance can be effectively reduced, and the heat dissipation efficiency of the electric cabinet can be improved. Moreover, shutters 31 can effectively prevent water vapor from entering box body 1 which damages the electrical components and affects the normal operation of the air conditioner.

In an embodiment, there are a plurality of air vents 21, and the plurality of air vents 21 are closely arranged on bottom plate 2.

After wind enters cavity 4 from shutters 31, it flows out from the plurality of air vents 21 arranged on bottom plate 2. The more the air vents 21 are, the faster the wind flows out, which can further improve the heat dissipation efficiency of the electric cabinet, making the ventilation and heat dissipation effect of the electric cabinet better.

In an embodiment, sizes and shapes of air vents 21 are different from each other.

There are a plurality of air vents 21 with different sizes and shapes. Air vents 21 can be set larger in some parts where strong heat dissipation is required, so as to speed up wind from air vents 21 into box body 1 and improve the heat dissipation efficiency of the electric cabinet.

In an embodiment, slats of shutters 31 are opened downwards.

As shown in FIG. 5, the slats of shutters 31 are opened downwards and form a certain angle with box body 1, thus preventing rainwater from entering cavity 4 and then entering box body 1 when rain is falling, so as to prevent rainwater from damaging the components in box body 1.

In an embodiment, air inlets 311 and air outlets 312 are formed between the slats of shutters 31 and ventilation cover plate 3, and air outlets 312 are aligned with air vents 21.

As shown in FIG. 5, wind enters cavity 4 through air inlets 311 and air outlets 312 of shutters 31. Because air outlets 312 are aligned with air vents 21, wind may flow directly from air vents 21 into box body 1 without turning to improve the heat dissipation effect of the internal components of the electric cabinet.

In an embodiment, air outlets 312 are communicated with cavity 4.

Air outlets 312 on shutters 31 are communicated with cavity 4, thus wind enters from air inlets 311 and flows directly into cavity 4, and then flows into box body 1 through air vents 21 to conduct heat dissipation for the electrical components in box body 1.

In an embodiment, there are a plurality of shutters 31, and the plurality of shutters 31 are arranged in an array on ventilation cover plate 3.

As shown in FIG. 3, there are a plurality of shutters 31; wind enters cavity 4 from shutters 31 and then enters box body 1 to conduct heat dissipation for the components, and therefore, setting the number of shutters 31 as multiple can increase the air volume, so that more wind can be achieved inside box body 1, and the heat dissipation efficiency of the electric cabinet can be further improved.

In an embodiment, air outlets 312 of shutters 31 are each aligned with at least one air vent 21.

Hence, all the wind entering from shutters 31 can flow into box body 1 directly through air vents 21 without turning in cavity 4 to conduct heat dissipation for the components in box body 1 and improve the heat dissipation efficiency.

In an embodiment, the slats of the plurality of shutters 31 are opened in the same direction.

As shown in FIG. 5, the slats of the plurality of shutters 31 are arranged in the same direction. When rainwater is falling, it can prevent rainwater from entering cavity 4 and then entering box body 1, avoiding that part of rainwater enters box body 1 from air inlets 311 when shutters 31 are opened in the reverse direction, causing damage to the components in box body 1.

This disclosure further provides an air conditioner, and the air conditioner is provided with the above electric cabinet of an air conditioner. Since the air conditioner has the above electric cabinet of an air conditioner, and the electric cabinet of an air conditioner has above advantages, by setting the electric cabinet of an air conditioner, the air conditioner has corresponding advantages. Therefore, the air conditioner of this embodiment has good ventilation and heat dissipation effects, good electric control and rainproof effects, low air duct resistance, and high electric cabinet heat dissipation efficiency.
